结合工程实例,从施工工艺控制、过程管理等方面对现阶段地下工程现浇混凝土结构在施工过程中存在的质量问题及产生的原因进行了详细的分析。针对地下工程在止水带安装、施工缝凿毛清理、混凝土浇筑振捣及收面、钢筋加工及安装等施工环节存在较多质量问题的现状,通过加强现场施工管理与控制,提高质量意识,采取规范化、精细化处理施工缝的同时对混凝土工程进行二次振捣、二次收面等施工措施,解决当前地下工程现浇混凝土结构存在的质量问题,为今后地下工程施工管理及施工过程控制提供借鉴,提前预防类似工程质量问题的发生。
Combined with the engineering examples, the quality problems and the causes of cast-in-place concrete structures in the underground construction at the present stage are analyzed in detail from the aspects of construction process control and process management. In view of the current situation that there are many quality problems in construction of water-stop belts, cleaning of construction seams, concrete pouring and vibrating and confined surfaces, reinforcing steel processing and installation, etc., the construction quality of the underground works is enhanced by strengthening on-site construction management and control, To take a standardized and meticulous treatment of construction joints at the same time secondary concrete vibram five fingers vibram five fingers vibram five fingers vibram five fingers second face and other construction measures to solve the current underground construction of cast concrete structures existing quality problems for the future underground construction management and construction process control Provide reference, to prevent similar projects in advance the occurrence of quality problems.
